-This module provides the searching facilities for the Koha MARC catalog
+=head1 findsuggestion($dbh,$values);
-C<&catalogsearch> is a front end to all the other searches. Depending
-on what is passed to it, it calls the appropriate search function.
+=head2 $dbh is a link to the DB handler.
-=head1 FUNCTIONS
+use C4::Context;
+my $dbh =C4::Context->dbh;
+
+=head2 $values is a word
-=over 2
+Searches words with the same soundex, ordered by frequency of use.
+Useful to suggest other searches to the users.

+
+=head2 $dbh is a link to the DB handler.
+
+use C4::Context;
+my $dbh =C4::Context->dbh;
+
+$tags,$and_or, $excluding, $operator, $value are references to array
+
+=head2 $tags
+
+contains the list of tags+subfields (for example : $@tags[0] = '200a')
+A field can be a list of fields : '200f','700a','700b','701a','701b'
+
+Example
+
+=head2 $and_or
+
+contains a list of strings containing and or or. The 1st value is useless.
+
+=head2 $excluding
+
+contains 0 or 1. If 1, then the request is negated.
+
+=head2 $operator
+
+contains contains,=,start,>,>=,<,<= the = and start work on the complete subfield. The contains operator works on every word in the subfield.
+
+examples :
+contains home, search home anywhere.
+= home, search a string being home.
+
+=head2 $value
+
+contains the value to search
+If it contains a * or a %, then the search is partial.
+
+=head2 $offset and $length
+
+returns $length results, beginning at $offset
+
+=head2 $orderby
+
+define the field used to order the request. Any field in the biblio/biblioitem tables can be used. DESC is possible too
+
+(for example title, title DESC,...)
+
+=head2 RETURNS
+
+returns an array containing hashes. The hash contains all biblio & biblioitems fields and a reference to an item hash. The "item hash contains one line for each callnumber & the number of items related to the callnumber.
+
+=cut
+
+=head2 my $marcnotesarray = &getMARCnotes($dbh,$bibid,$marcflavour);
+
+Returns a reference to an array containing all the notes stored in the MARC database for the given bibid.
+$marcflavour ("MARC21" or "UNIMARC") determines which tags are used for retrieving subjects.
+
+=head2 my $marcsubjctsarray = &getMARCsubjects($dbh,$bibid,$marcflavour);
+
+Returns a reference to an array containing all the subjects stored in the MARC database for the given bibid.
+$marcflavour ("MARC21" or "UNIMARC") determines which tags are used for retrieving subjects.
